<div>Hi,</div>
<div><br>
</div>
<div>A couple of comments:</div>
<div><br>
</div>
<div>i) A simple "Killed" message is the Linux kernels way of saying it catastrophically ran out of memory. On my machine, I'm getting the marginally more descriptive "fatal:NclMalloc Failed:[errno=12]" message. In any case there 59709 lines in that first January
file, and you are trying to create a 59709x59709 array of floats, and that's about 14GB which is more than my 16GB machine can accommodate.
<br>
</div>
<div><br>
</div>
<div>ii) Are these irregularly spaced observational data? Why the nlon x nlat square array?</div>
<div><br>
</div>
<div>iii) I'm confused about the use of proj4/translate_coordinate? You're data are already in decimal degrees -- why project the values into an equidistant projection?
<br>
</div>
<div><br>
</div>
<div>iv) I don't understand this question: "...<span style="font-size:12pt; font-family:Calibri,Helvetica,sans-serif"> it is possible to make this projection (spatialization of these data) in the same resolution as another data in netcdf (spatial reference)
and using a shapefile for a more specific region?"</span></div>
